I am not sure if anyone esle is having this problem going from 8.0.2 FOSS to 8.0.6 FOSS. But when the upgrade on my proxies have finished, we cannot send or recieve mail. Complains about port 10024 being unreachable (amavisd).

I got a solution here for anyone who runs into this and obviously the error message makes it pretty obvious, but why not.

If you su - zimbra
zmamavisdctl restart

You will see the error:

[zimbra@proxy2 ~]$ zmamavisdctl restart
Stopping amavisd...amavisd is not running.
Starting amavisd...Error in config file "/opt/zimbra/conf/amavisd.conf": syntax error at /opt/zimbra/conf/amavisd.conf line 59, near "= ;"

Just edit /opt/zimbra/conf/amavisd.conf.in, find this line

Change
$log_level = %%amavisloglevel%%; # I forget what the original value was..But the variable was blank, so it caused this error.
to:
$log_level = undef; # I don't know which the default log level is, but this works.

Anyway hope this helps someone
